SECURITY INDICATOR

Warns that the vehicle has NATS.

In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition
switch ON or START position. In the vehicle with Intelligent Key system, security indicator always flashes
with mechanical key removed condition (key switch OFF) and ignition knob released condition on LOCK
position (ignition knob switch OFF).
NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Security Indicator
WITHOUT INTELLIGENT KEY SYSTEM
WITH INTELLIGENT KEY SYSTEM

In ignition knob operation with Intelligent Key, it always turns off with pushing ignition knob, and always
flashes with ignition knob released (ignition knob switch OFF) condition on ignition knob “LOCK” position.

In ignition knob operation with mechanical key, it turns off on the condition that mechanical key is inserted
in key cylinder, and always flashes with ignition knob released (ignition knob switch OFF) condition on
mechanical key removed condition.
System CompositionBIS000YD
The immobilizer function of the NATS consists of the following:

Ignition key (models without Intelligent Key system)

Mechanical key (models with Intelligent Key system)

NATS antenna amp.

Steering lock unit. (models with Intelligent Key system)

BCM

BRAKE TUBE AND HOSEPFP:46210
Hydraulic CircuitBFS000FY
CAUTION:

All brake tubes and hoses must be free from excessive bending, twisting and pulling.

Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.

Brake tubes and hoses is an important safety part. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe off them and wash it away with water
immediately.

Do not bend or twist brake hose sharply, or strongly pull it.

When removing components, cover brake line connections so that no dirt, no dust, or other for-
eign matter gets in.

Refill with new brake fluid “DOT 3 or DOT4”.

Do not reuse drained brake fluid.

CAUTION:
Align the matching marks of disc rotor and wheel hub,
which were marked at the time of removal when reusing
disc rotor.
2. Install brake caliper assembly to vehicle, and tighten torque
member mounting bolts to the specified torque. Refer to BR-26,
"Components" .
CAUTION:
Before installing torque member to vehicle, wipe oil and
grease on washer seats on steering knuckle and mounting
surface of torque member.
3. Install brake hose to brake caliper assembly, and tighten union bolts to the specified torque. Refer to BR-
26, "Components" .
CAUTION:

Do not reuse copper washers for union bolts.

Connect brake hose aligning with caliper assembly mounting protrusion.
4. Refill with new brake fluid and bleed air. Refer to BR-10, "
Bleeding Brake System" .
5. Check front disc brake for drag.
6. Install tyres to vehicle.
Disassembly and Assembly of Brake Caliper AssemblyBFS000C1
NOTE:
Do not remove torque member, pads, shims, inner shim cover, and pad retainers when disassembling and
assembling cylinder body.
DISASSEMBLY
1. Remove caliper assembly from Vehicle. Refer to BR-28, "Removal and Installation of Brake Caliper
Assembly" .
2. Remove sliding pin bolts, from cylinder body, and remove pads
shims shim cover and pad retainers from torque member.
CAUTION:

When removing pad retainers from torque member, lift
pad retainer in the direction by the arrow (shown in the
figure) so as not to damage it.

Do not drop pads, shims, inner shim cover and pad
retainers from torque member.
3. Remove sliding pins and sliding pin boots from torque member.
